this could be a valid approach in .net core credit:-https://forums.asp.net/t/2154835.aspx?Tracking+active+or+logged+in+users public static class TrackUsers { private static ConcurrentDictionary activeUsers = new ConcurrentDictionary (); private const Timeout = 20; public static void UpdateUserAccess(string userName) { var now = DateTime.Now; activeUsers.AddOrUpdate( userName.ToLowerCase(), now, (k,v) => now ); } public static bool IsUserActive(string userName) { DateTime lastAccess; if (activeUsers.TryGetValue(userName.ToLowerCase(), out lastAccess)) return lastAccess.AddMinutes(Timeout) >= DateTime.Now; return false ; } public static List ActiveUsers() { var now = DateTime.Now; activeUsers.Values() .Where(r => r.AddMinutes(Timeout) >= now) .Select(r => r.Key) .ToList(); } }

Hi, I guess you can achieve that by manually tracking active user count (in ASP.Net MVC) as below. public static int count = 0; //for count of visitors public void Application_Start(Object sender, EventArgs e) { Application[ "activeUsers" ] = count; } public void Session_Start(Object sender, EventArgs e) { count = Convert.ToInt32(Application[ "activeUsers" ]); Application[ "activeUsers" ] = count + 1; } public void Session_End(Object sender, EventArgs e) { Application[ "activeUsers" ] = count - 1; count = Convert.ToInt32(Application[ "activeUsers" ]); }

Hi Sourabh, Try this code: Controller: public class HomeController : Controller { private ApplicationDbContext _context; public HomeController(ApplicationDbContext context) { _context = context; } public IActionResult Index() { return View(); } public IActionResult About() { ViewData[ "UserCount" ] = _context.Users.Count(); ViewData[ "Message" ] = "Hello Word" ; return View(); } } View: @{ ViewData["Title"] = "About"; } h2 > @ViewData["Title"]. h2 > h3 > @ViewData["Message"] h3 > p > Use this area to provide additional information. p > button > @ViewData["UserCount"] button >
